Service Miscellaneous
Using Proper Fuel
Use regular grade unleaded fuel with an octane rating of 87
octane or higher. Fuel blends containing up to 10% ethanol
or up to 15% MTBE reformulated fuel are acceptable. Do

not use fuel or additives containing methanol as engine
damage can occur.
Always use fresh, clean fuel that is purchased in a quantity
that can be used within approximately 30 days, or add fuel
stabilizer.
Fuel is blended to give best seasonal performance. To
avoid engine performance problems such as hard starting
or vapor lock, use in-season fuel. Use fuel during warm
weather that was purchased during that season, and use
fuel during cold weather that was purchased during that
season.
Fuel can become stale in machines with engines that are
used seasonally or infrequently during a season. Stale
fuel can produce varnish and plug carburetor components
which can affect engine performance.
Keep fuel storage container tightly covered and in a cool
area out of direct sunlight. Fuel can break down and de-
grade if not sealed properly or exposed to sun and heat.
Condensation may collect in the fuel tank because of a
variety of operating or environmental conditions and, over
time, may affect your machine’s operation. Fill fuel tank at
the end of daily use and store fuel in plastic containers to
reduce condensation.
For best year-round performance and fuel-handling, add
stabilizer to fuel immediately after fuel purchase. Such
practice helps prevent engine performance problems and
allows fuel storage in the machine all year without draining.
Filling Fuel Tank
CAUTION: Avoid injury! Fuel vapors are
explosive and flammable:
Shut engine off before filling fuel tank.
Do not smoke while handling fuel.
Keep fuel away from flames or sparks.
Fill fuel tank outdoors or in well ventilated area.
Clean up spilled fuel immediately.
Use clean approved non-metal container to
prevent static electric discharge.
Use clean approved plastic funnel without
screen or filter to prevent static electric dis-
charge.
